To all whom t may concern.'

Be it known that we, MARGARET GIVLER andBoBEET CHENAULT GIVLER, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and'useful Improvement in Photographic Cameras, -of which the following is a specification.

Our invention relatesjto improvements 1n photographic cameras, and the object of our invention is to provide a photographic camera which shall embody mechanism that shall be adapted to be operated to cause a plurality of contiguous portions of a sensitized photographic ilm, each portion in quick succession, to be exposed momentarily to the action of its lens whereby a plurality of photographic negatives may be produced on Said film each of which negatives shall represent a different view of moving objects or a like view of stationary objects that may be disposed in front of said lens, said mechanism being actuated continuously during such operation.

A further object of our invention is to.

provide a camera which shall embody devices for adjusting the focal distance between the exposed portion of a lilm and the lens', properly .to correspond with the distance between the camera and the objects to be photographed, which devices shall be so formed and disposed that the exterior dimensions of the camera shall be small in proportion to the maximum effective focal distance between its objectilens and the exposed-portion of the film.

We accomplish these objects by mechanism illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of a camera embodying our invention;

F ig. 2 is an enlarged view of the same in vertical section on broken line 2, 2 of Fig. 4;

Fig. 3 is an enlarged view of the same with its top wall removed; and

Fig. 4 is an' enlarged view of the same in vertical section on broken line 4, 4 of Fig. 2 whereby internal parts are shown in front elevation.

Referring to the drawings, throughout which like reference numerals indicate like parts, a rectangular inclosing case is formed to have a top Wall 6, a vertical rearward end wall 7, a vertical front end wall 8, vertical side walls 9 and l0. and a bottom Wall 1l which is provided with knobs, like knobs 12 and 13, that are fixed to its under side .to serve as feet for supporting the case in a position spaced from any surface upon which the camera may be Adjacent tothe side end wall 8 is provided the rearward end wall 7 is provided with double doors 15 and 16, while the side wall 9 is provided with a door 17 which extends from a vert-ical line near the rearward end wall 7 for about two thirds'of the distance therefrom to the front end wall 8.

Fastened to the underside of the top wall 6 are two grooved guiding cleats 18 and 19 which are disposed to extend transversely from a line near the top of the door 17 -for a distance nearly half way across the case, the cleat 18 being spaced a short distance from the rearward end wall 7 and the cleat 19 being near the center of the lengthwise distance of the case.

rlhe upper side of the bottom wall 11 is provided with guiding grooves 20 and 21 which are parallel with and directly under the 1grooves of the cleats 18 and 19 respective v.

placed. wall 10, the front with a door 14, and

Disposed parallel with and slightly spaced i from the inner side of the door 16 1s a partition 22 that extends from the bottom wall 11 to the top wall 6 and whose width extends from a. point nearv the edge of the door 15 for about two thirds of the distance to the hinged edge of the door 16, as indicated in Fig. 3.

Directly opposite the partition 22 and parallel therewith and widely spaced therefrom is a like vertical partition 23 whose vertical edge (that is nearer the side wall 10) joins the vertical edge of a partition 24 that extends at a right angle therefrom for a distance directly toward the front end Wall 8 thence in a curve toward the side wall 9 through and beyond the quadrant of a circle, thence again directly toward the wall 8 to unite therewith, as indicated by full lines and dotted lines in Fig. 3 and by full lines in Fig. 4.

Adjacent to the wall 8 a small portion of the upper part of the partition 24 is provided with an offset 25 as indicated in Fig. 4.

Extendingacross the corner of the interior of the case at an angle of 45 degrees from the side wall 10 to the nearer edge of the partition 22 is a mirror 26 which serves as a partition to form a triangular compartment 27 in addition to serving as a reliector to cause any rays ot light entering the case through the door 14 to be reflected at a right angle directly toward the plane of the door 17.

As indicated by dotted lines in Fig. 3 and by full lines in Fig. 4, a vertical partition 28 is disposed to extend from the partition 24 to .the side wall 10 which. partition 28 is provided with a circular opening therethrough, which opening is of a diameter indicated by dots 29 in Fig. 3, and on that side of it nearer the door 14 is fastened one end of extensible walls 30, of accordion-like construction, whose other end is fastened to the rearward side of a rectangular box 31.

' Fastened to the front side of a rectangular box 31 is a photographic lens box 32 that contains lenses and operative shutter mechanismot forms well known to those skilled inthe art, said lens box 32 being disposed directly opposite the doorway of the door 14.

The front and back walls of the box 31 are provided with openings therethrough so that when the door 14 is wide open andthe shutter of the lens box 32 is actuated to open then rays of light may extend through the lens box 32, the box 31 and between the extensible walls 30 to impinge/on the mirror 26.

Joined to the upper edge portion of the mirror 26, the partitions 22, 23, 24 and 28 and to the side wall 10, and slightly spaced from the under side of the top wall 6 is a horizontallyV disposed plate 33.

Disposed telescopically to ylit within the space between the partitions 22 and 23 is a rectangular frame 34 upon whose outer top and bottom edge portions are fastened transverse metal plates 35 and 36, respectively,

Whose opposite end portions are provided with tongues 37 land 38 and tongues 39 and 40, respectively, which are slidably disposed in the grooves of the cleats 18 and 19 and in the grooves 20 and 21 of the bottom wall 11, respectively, whereby the frame 34 may be guided in its sliding movements toward and away from the mirror 26.

With its ends 'pivotally mountedin 'the outer end portions of the tongues 37 and`39 is a vertically disposed roller 41, and in a like manner a roller 42 is rotatably,disposed to extend between the outer end portions of the tongues 38 and 40. j

Slidably mounted on the upper side of the plate 33 is a rack-bar'43 that is guided in its endwise movements by guide-strips 44, as shown more clearly in Fig. 3, and one end portion of said rack-bar 43 is fastened to the central portion of the metal' plate 35 whereby. endwise movements of said rackbar 43 shall cause the frame 34 to move toward or away from the mirror 26.

Also slidably mounted on the upper side ot the plate 33, to extend in a direction at right angles to the rack-bar 43, is another inviata rack-bar 45 which is guided in its endwise movements toward and away from the mirror 26 by guide-strips 46 and one end portion of said rack-bar 45 is fastened to the central portion of the top wall of the rectangular box 31, whereby the lens box 32 shall be moved rearwardly and rontwardly in response to endwise movements of said rack-bar 43.

As shown in Fig. 3, therack-bars 43 and 45 are each provided with teeth on their adjacent end edge portions, the teeth of the rack-bar 45 being in operative engagement with a pinion 42' that is pivotally mounted on the plate 33, while the teeth of the rackbar 43 are in operative engagement with the teeth of a segment 48 of a gearwheel that is also pivotally mounted on the plate 33, the teeth of said segment 48 being also in operative engagement with the teeth of the pinion 47, whereby a rotative movement of the segment 48 in a clockwise direction will cause both the lens box 32' and the frame 34 simultaneously to move toward the mirror 26,l while a rota-tive movement of it in afcontra-clockwise direction will cause said lens box 32 and said trame 34 both to move in a direction away from said mirror 26.

, Attached to t-he segment 48 is an arm 49 which extends forward therefrom to terminate in a pointer 50 that is exposed through an opening 51, of the form of a segment of a circle, that extends through the top wall 6 of the case, and through which opening 51 ones linger may gain access to the end portion of the arm 43 in the operation of moving said arm 49 to cause the rack-bars 43 and 45 to approach or recede from the mirror `26.

'The segmentally formed opening 51 is provided with an escut/'cheon 52 that is fastened on the upper surface of the top wall 6, and upon said escutcheon 52 is inscribed numbers and the division marks of a scale, as shown in Fig. 1, which numbers and division marks represent diii'erent' distances, in feet, between the camera and objects to be photographed, and said division marks are so relatively disposed that a movement of the pointer 50 to any particular one of said division marks shall cause the lens box 32 to be disposed at the proper focal distance from, the mirror 26 for taking pictures of objects that are at the same distance from the camera that is indicated by that particular one of said division marks.

A gearwheel 53 is fastened to a shaft 54,

which is rotatably mounted in bearings formed in two spaced frame plates 55' and (LTR.

AlS

Mounted on the sheit 78 is e gearwheel 8l Whose teeth ere removed trom oppositely disposed segmental portions thereof, es shown more clearly in Fig. 2, said geer- Wlieel 8l being so` disposed thet the series of teeth on eech of the other two oppositel f disposed segmental portions shell succesf siyely ine-lie operative engagement with the teeth ot the geerwheel 75 in response to o rotation of the shaft 78whieh vrotation tney be en'eeted hy turning the crank '80.

Thus e oontinuous rotation of the shaft 578 in en ohyions manner will permit the geen. Wheel l5 to stop twice during eech revoluoif seid shaft 7 8 with the result that the cylinder 58 will. rotetively niove interinit'-" to 'to Wheel 8l. is oi such length es will cause the 88 to he intermittently moved for e diseqnel to the distance between the peritions 22 28.

Articulated to the lei/er 84 is the' loner end of e connecting tod 8'? Whose upper end is articulated With another lever 88 one end of which is hinged to thev side oie the pertition 2d, es more clearly shown in Fig.. d, and the other end of which is disposed to adept it operatively to enge-ge with the shutter tneting lever 89, ofthe lens loon whereby a depression of seid leser 88, to its position indioeted by dotted lines in seid Fig. d, will conse the shutter eotneting lever 89 to operste the shutter of the lens bon 88 in a Well so disposed on the et rest'in e position to receive rays of lll@ whose periphery 1s provided with equally spaced numbers and which is'provided with a notched flange 92, which disk is mounted on a shaft 93 that is rotatably disposed in" bearing brackets 94 and 95 that are secured respectively to the partition 24' and the front end wall 8 in positions to adapt the notched flange 92 to project u wardly through a slotted opening 96 that extends throu pressed portion of ,thetop wall 6 adjacent to the front end wall 8, said slotted opening being of such width as will expose to view any one of said numbers that may be opposite said slotted opening. v

Also fastened on the shaft 93, adjacent to the disk 91, is a ratchetwheel 97 with which lis associated two spring-like pawls 98 and 99, which ratchetwheel 97 and pawls 98 and 99 are more clearly shown by dotted lines in Fi 4.

ghe pawl 98 is fastened to the underside of the top wall 6, while the pawl 99 is attached to the lever 88, whereby each depression of said lever 88 will rotatively move the ratchetwheel 97 one tooth forward, the

number of teeth in the ratchetwheel 97. being equal to the number' of units inscribed on the periphery of the disk 91.

lf it be desired to set the disk 91 to zero, at any tim, it is only necessary to engage ones finger with the notches of the flange 92 and thereupon move the disk in a contraclockwise direction until the zero character is exposed to view; and thereafter each numeral that is successively exposed will, in an obvious manner, indicate the number of portions of the film 66 that has been exposed. y

In the upper right hand corner of the front end of the case is a finder 100, of a well known form of construction, there being provided a circular hole 101 in the door 14 in a position opposite the lens of said finder 100, the osition of which hole 101 yis indicated by Ibroken circular lines in' Fig. 4.

The operation of our camera when constructed in accordance with the accompanying drawings may be described as follows:

A roll of sensitized photographic film is rotatably disposed, in an obvious manner, in the compartment 27 whereupon its outer end no ray of light throughthe slot I which free end portion of the lever /84' gh a del portion .is extended to engage withthe rollers' 62, 41 and 42, thence to be attached to the periphery the arm 49 is moved to'cause the pointer '50 to register with the division mark of the numeral representing camera and the objects to be photographed with the result that the lens box 32 and the frame 34 lwill both be, moved to 'a proper focal distance with respect to themirror 26. Then the disk 91 is moved to expose the zero character, whereupon the objects to be photographed may be observed through the finder 100, in a well known manner, and thereupon the door 14 is opened wide. v

Then, the camera bein in a position to photography the desired o jects, which may 'of the cylinder '58 and thereupon the distance-between the tinuously turned until a numeral on` the disk- 91 is exposed that represents the required number of' exposures of successive portions ofthefilm66. l

Each revolution of the crank 8O will cause the film 66 to be intermittently moved to expose two portions of the lm 66 and while each of said portions is at rest for a moment the shutter of the lens box 32 will be openedv for a moment by the action of the lever 88 on the shutter actuating lever 89, thereby to permit the object lens of the lens box 32 to be exposed to the objects to be photographed, the image of which objects will be reflected from the mirror 26 against the sensitized side of that portion ofthe ilm66 which at the time isI at rest opposite the space between the partitions 22 and 23.

Thus, when the required 'number'of ex-A posures of the successive vportions of the ilm 66 have been made, as indicated by anumeral on the periphery of the disk 91, then the crank 80 may be removed and -the door 14 closed until other objects are to be photographed. A

When all portions of the film 66 have been exposed, then the entire film 66' will be wound on the cylinder 58, whereupon the door 61 may be opened to swing'downw'ardly to permit the cylinder 58 to drop through the bottom wall 11 thereby to extract said cylinder 58 from the case.

Obviously, changes may be made in the forms, dimensions and arrangement of parts of our invention without departing from the spirit thereof.
